Abstract: In order for a medium for the production of viable, fused cells by means of field-induced electrical fusion whereby the medium exhibits a pH value compatible for the cells to be fused and comprises a largely isotonic aqueous solution of non-electrolytes and electrolytes and the ratio of concentration of non-electrolytes to electrolytes in the solution is at least 10:1, to be improved to such an extent that clearly higher yields of viable, i.e. division-capable, fused cells are obtainable, it is proposed that the non-electrolyte part be composed essentially of at least one multiply substituted derivative of one or more of the basic chemical building blocks cyclohexane, tetrahydrofuran and tetrahydropyran, whereby the cyclohexane derivatives exhibit at least two hydroxyl groups and the tetrahydrofuran as well as the tetrahydropyran derivatives exhibit at least one hydroxyl group and one amino group as substituents on the ring and/or on an aliphatic side chain, and that the isotonic property of the solution be constantly guaranteed by the overall osmolarity of the electrolyte and non-electrolyte parts.

Title: Service boom
Inventor: WEERD WILLEM MARINES DE
IPC: B66C23/20
Filed: 1987-03-09
Abstract: There is described a service boom adapted to be mounted to a wall (6) at one of its ends for pivotal movement about a vertical axis. The boom has two sections (2,3) hinged together about a further vertical axis, each boom section comprising two vertically spaced tubes (8,9,13,14) joined at their respective ends. Supply cables and lines pass along the interior of one of the tubes to a housing (7) at the free end of the boom, where outlet sockets (33,34) are located. The other tube serves to conduct exhaust gases to an extractor. As the joint (4) between the boom sections (2,3), flexible bellows portions (18,19) are provided to connect the respective upper (8,13) and lower tubes (9,14) of each boom section (2,3). The pivotal mounting and the hinged joint are provided with synthetic bushes (47) and washers (27) to ensure that the friction at the hinge is less than that at the pivot.

Title: Window management
Inventor: TREVETT NEIL FRANCIS
IPC: G09G5/14
Filed: 1988-03-23
Abstract: A method for performing window management using simultaneously accessable screen refresh (102) and off screen (104) memories which have the ability to perform image data translation and high speed copy operations. Each window written to the screen refresh memory 102 (Fig 2) is simultaneously written to the off screen memory 104 (Fig 3) at an offset (110) selected so as to insure that no two windows will overlap even though they overlap in the screen refresh memory. An obscured portion of a background window is reconstructed by performing a block copy of the obscured portion form the off screen memory to the screen refresh memory. Further, windows can change from background to foreground through a similar copying proceedure. Animation and other effects can also be accomplished. <IMAGE>

Title: Protective coatings
Inventor: FARMER GILBERT
IPC: C23C4/02
Filed: 1988-09-29
Abstract: Protective coatings such as ceramic coatings, which serve as thermal barriers, are applied to metallic substrates by first roughening the substrate surface to provide recesses in the surface which are jagged and which extend into the substrate at least about 600 microinches, the recesses being connected to the surface, and then disposing the protective coating in the recesses so that the coating is mechanically interlocked with the substrate at the recess. Preferably, the substrate surface is roughened by either electro-chemical machining or chemical etching. Convenient methods for applying a ceramic coding include plasma spraying, vapor deposition, and sputtering. In one embodiment, the substrate material is chosen from the group consisting of nickel-base, cobalt-base, and iron-base alloys, and the ceramic coating material is zirconia stabilized with another oxide. The protected article finds use in aircraft engine applications.

Title: Process and device for measuring a torque applied to a formed member e.g. shaft
Inventor: LANGEN HANS-JUERGEN
IPC: G01L3/10
Filed: 1989-05-15
Abstract: Torque on a shaft 1 is determined by generating two sets of cyclically-varying measured values (e.g. as represented by triangular waveforms in Figure 3) whose difference is related to the torque which can thus be determined during rotation. A determination can also be effected during torque-loaded stationary conditions of the shaft. The values may be generated by using toothed wheels 2,3 and proximity sensors 5, 6 or, alternatively, annular coded magnetic tapes and co-operating sensing elements. <IMAGE>

Title: Fabricating electrical components involving vapour deposition of polymers
Inventor: STREET KENNETH
IPC: H01B13/06
Filed: 1990-09-22
Abstract: A method of fabricating an electrical component includes deposition onto a conductive part which may be of gold, within an evacuated chamber, and from the vapour state, a polymer having a high dielectric constant, curving the polymer in situ on the conductive part and providing a conductive layer, eg of gold on the layer of dielectric material. A suitable polymer is a para-xylylene polymer. The conductive layer, and/or the conductive part, may comprise a mask, or other masks may be used, so that portions of the deposited layer of dielectric material can be removed selectively or it can be a capacitor or a coaxial cable. The fabricated electrical component can be small enough to comprise a socalled micro- electronic component. Alternatively, or in addition, the electrical component may be small enough to be capable of being coupled satisfactorily to associated micro-electronic components within a circuit assembly.

Title: Brake pressure control device for automotive vehicles
Inventor: SCHONLAU JUERGEN
IPC: B60T13/12
Filed: 1991-02-04
Abstract: A vehicle brake pressure proportioning device with inlet(s) (2) and outlet(s) (3) has a regulating piston (7) which cooperates with a valve closing member (9) supported within a slidable control piston (8) to form a proportioning valve, the control piston tending to move upwards under braking pressure to open the valve while such movement is interrupted by means of a valve (21) when an inertia member (24) responds to a predetermined vehicle deceleration. A multiple-stage restrictor (26) is positioned in the inlet region to prevent the actuating velocity of the brake influencing the changeover pressure. The flow area of the restrictor increases as the pressure build-up velocity rises, e.g. by having parallel or coaxial passages one of which is closed below a certain build-up velocity. <IMAGE>

Title: Monitoring smoke and dust in air
Inventor: BUSH MICHAEL ARTHUR
IPC: B01D29/09
Filed: 1991-03-14
Abstract: A reel of filter paper (1) is typically clamped between two halves (2, 2A) of a chamber driven together by pneumatic ram (9). After a preset period of time, the ram separates the filter chamber so that the accumulated "stain" on the filter paper can be precisely moved underneath e.g. a reflectometer (4). A combination of unused and used filter paper reflectometer readings and the airflow values, are used to arrive at the weight of accumulated particulates using a known algorithm. The airflow through the system can be developed by pump (12) and the precise value set by needle valve (13). During the monitoring period the chamber is clamped and the airflow is on. During the measurement period the chamber is unclamped and the airflow turned off. <IMAGE>

Title: Weighing balance
Inventor: MULLIGAN BRIAN NEIL
IPC: G01G21/10
Filed: 1991-04-03
Abstract: The invention concerns an analytical balance having a weigh pan (1) connected to a balance mechanism (6, 7, 10) by a pan spigot (3). The pan spigot (3) is biased by spring means (5) which is preset to allow tilting movement of the pan spigot (3) should excessive force be applied to the weigh pan (1). When the spigot (1) undergoes a predetermined degree of tilting by an unwanted force A or B, a disc 4 attached to the spigot is pivoted about its edge against the resilience of the spring means (5) and causes the spigot to engage a guard means (2), which in turn transmits a force to an outer housing (8) of the balance so that the unwanted force applied to the spigot is not transmitted to the balance mechanism. <IMAGE>
